EDMOND PRUDHOMME AND PANTALEGN MOSES LEPROHON, OF

NEW YORK, N. X.

Leners Patent No. 90,193,1zated May 1s, 1869.

MROVED SLIDIN G- DOOR To all whom itmay concern:

Be it known that we, EDMOND PnUDHoMME and PANTALON Moses LEPROHON, ofthe city, county, and State of New York, have invented a new and usefulImprovement in Sliding Doors; and we do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to make and use the same, reference`being had to th'e accompanying drawings, forming part of-thisspecication, in which- Figure 1 represents a face View, partly insection, of our improvement in sliding door.

Figure 2 is an edge view, partly in section, of the same. v l

Similar letters of reference indicate corresponding parts.

This invention relates to a new means for retaining sliding doorsbetween their guides, even if they should shrink or settle irregularlyor evenly; and has for its object to overcome the frequent annoyanceresulting from the working of the upper dowel-pins out of the groove, ortrack provided for them.

The invention consists in providing rollers on the upper edges ofsliding doors, said rollers being hung in frames or bars, that rest onsprings, provided on or in the door, so that by means of these springs,the rollers are constantly held up against the upper frame, and retainedin the groove provided for them.

lf the door or frame should shrink ever so much, the upper rollers willalways be retained in their grooves, or .on their tracks, and the doorwill consequentlyalways be properly guided.

A, in the drawing, represents a sliding door;

B is the side frame, between which it moves;

C isithe rail, on which it rests; and

D is the upper frame or lintel.

Rollers a a are arranged on the lower edge of the door, to travel on therail O. b b are rollers, hung, with their axles c, in the bifurcatedupper ends oi' metallic bars E, which bars are, with their shanks d,iitted into mortises, provided in the upper edge of the door.

Springs e e are arranged in these mortises, to snpport the bars E. Bythese springs the rollers b are held constantly against the lintel D, inthe groove, or on the track provided for them, and if the door or frameshould shrink `or settle, the rollers will adjust themselves up or downas they travel along under the lintel.

The door can thusnever work itself laterally out of the frame.

Having thus described ourinvention,

What we claim as new, and desire to secure by Letters Patent, is-

The rollers b, supported upon the springs e, in the upper end of asliding door, substantially as described, for the purpose specitied.
